allsorts VS image

But again you don't need to reinvent text layout from scratch (that's my discussion, BTW) if you use the platform's native text drawing facilities, like DirectWrite on Windows, or CoreText on macOS.

All these layers of Cows create an extremely complex lifetime tree and it's actually not possible to factor out the complex parsing steps into functions because they depend on a lot of stuff. (trying to return an OutlineBuilder from a function would dangling reference about 3 different temporaries, for example. Obtaining the temporaries is part of the parsing step)

machine learning, neural networks, image processing, cryptography (though it is getting better), font shaping/rendering (though it is getting better), CPU/software rendering (though it is getting better)

It can be used for the things you suggest but our driving use case is font parsing. The goal is to use it to generate the font parsing code in Allsorts, which is ultimately used in Prince.

Use allsorts or rustbuzz for text shaping

Loader -> Allsorts

It's something I'd like to improve on in future -- are there any pure-Rust libraries you'd recommend for shaping? Allsorts looks quite promising.

With the help of the image crate, loading an image from disk is fairly straightforward.

FTR there is a WebP decoder implementation in safe Rust in the image crate: https://github.com/image-rs/image

It used to be quite incomplete for a long time, but work last year has implemented many webp features. Chromium now has a policy of allowing the use of Rust dependencies, so maybe Chromium could start adopting it?

Hello! So I have a local app that I am currently running on desktop (windows). I'm using egui for the UI, and the program basically opens a folder, gets all the images in the folder, and then uses the image-rs library to resize and create a grid of images / some other operations.

png is the de-facto standard Rust crate for reading and writing PNG images, used e.g. by the image crate.

There's also a CLI to convert between formats. It uses the crate image.

exr is a is a 100% Rust and 100% safe code library for reading and writing OpenEXR images. It is used by the popular image crate to read and write OpenEXR.

We're currently looking for contributors to add support for zune-jpeg to the image crate. The image maintainers are open to it, but don't have the capacity to do it themselves. You can find more details here.

It would be helpful to contribute to the general change towards an untyped buffer with runtime representations for color space information and fallible conversions. (https://github.com/image-rs/image/pull/1718). It's currently stalling on having too few eyeballs to judge the impact and need for that complexity.

It uses https://github.com/1Password/arboard and https://github.com/image-rs/image under the hood. I haven't tested deeply but I assume it should handle many formats out of the box.
